Command Usage
• When creating a protocol-based VLAN, only assign interfaces via this
command. If you assign interfaces using any of the other VLAN
commands (such as
vlan on page -224), these interfaces will admit
traffic of any protocol type into the associated VLAN.
• When a frame enters a port that has been assigned to a protocol
VLAN, it is processed in the following manner:
- If the frame is tagged, it will be processed according to the standard
rules applied to tagged frames.
- If the frame is untagged and the protocol type matches, the frame
is forwarded to the appropriate VLAN.
- If the frame is untagged but the protocol type does not match, the
frame is forwarded to the default VLAN for this interface.
